Devices, methods, and networks that divide and proportionally distribute the drive strength of a clock buffer such that the output drive strength of the clock buffer is divided proportionally among a plurality of outputs from the clock buffer. In one embodiment, the present invention selectively couples adjacent parallel inverters present in a clock buffer to separate, internal distribution wires. The internal distribution wires are selectively coupled to one or more outputs by a connector wire to provide proportional, multiple outputs of the drive strength from the clock buffer to a clock network.

Dividing and distributing the drive strength of a single clock buffer

Coupling capacitance is used to balance skew in a network. In one embodiment, the coupling capacitance exerted by shielding wires oppositely adjacent one or more signal wires in a network is utilized to vary the speed of a signal carried on the one or more signal wires to balance skew in the network.
